IMPORTING PRODUCT ATTRIBUTE (BRAND)

Hello,

I am importing some products to WooCommerce by excel, all seems that work fine except the Attributes.

I would like to import the brand so I thought it could be a good idea to import as an Atribute, however, it doesn’t work.

In WC there is a parameter called Name of the attribute so I suposed here I have to write «Brand» and then there is another parameter called Value of the attribute and I suposed I have to write «Brand name».

But it doesn’t upload!

Is the attribute already created? Do I need to create first? What can I do?

THANK YOU
